I have two version of ruby installed 1.9 and 1.8.7(via macports) how do I make my app run with 1.8.7?

And How can i uninstall 1.9?

Solution

  • Firstly: switch to rvm it's excellent for ruby management

    If you don't want to then I believe you can remove the ruby package with (if installed with macports) with the following:

    sudo port uninstall ruby19

    To start using the new version of ruby you need to find where it is installed (it's something like /opt/local/<...>)

    Then go to the Binary folder and add it to path.

    export PATH=/opt/local/<...>:$PATH

    Removing the old one, you might need to change some env variables as well.

    Use RVM

    EDIT: added sudo to port command and changed standard location
